freedomxcruiser has asked for the wisdom of the Perl Monks concerning the following question:

here's the question. If any one could help me out that would be great.

2. Assignment 7 – The Currency Converter in Chapter 2, change the currency conversion program so that it asks for an exchange rate and three prices to convert.

Begin this exercise with the starter file in the Assignment zip folder.

Downloading Perl: Be sure to DOWNLOAD the latest version of PERL for your Operating System from the following link: Let your instructor know if you have any questions about installation. The file should be installed on the C: drive to a folder called Perl64 (this folder will be created automatically.)

    You must have PM confused with "The Lazy Students' Plagarism Sources."

    Good of you to state you question in a way that makes it utterly clear that you're asking us to do your homework.

    Good... that we don't do that. You'll learn little or nothing if we do it for you.


    we will help you if:
    • Your show some effort; ie, post your own code that begins to attack the problem. Be sure to include output and/or any errors or warnings.
    • Explain why the result is unsatisfactory... and
    • Ask for help on a specific problem. That, we'll be glad to steer you in the right direction.

    (You may also want to read such site-FAQs as On asking for help, How do I post a question effectively? and Writeup Formatting Tips.)

    Yet another gimmé request!
    Sorry, we expect SOPW to seek wisdom, not to ask us to do so for them.

    "...The Currency Converter in Chapter 2..."

    May be this is from Beginning Perl by James Lee?

    If so you find some sources here.

    But keep in mind what a wise prof told me many years ago: "Sure, you can cheat - if you really can explain the solution..."

    Do yourself a favor and find your own solution.

    On Windows
    perl -e "printf \"%.2f\n\",$ARGV[0]+0.005"
    Stored as $ARGV[0]; returned with two decimal place accuracy (with roundup) via printf.
